It was suggested that the rice pretreated by low energy ion implantation could enhance the antioxidation capacity and defensive ability when irradiated by UV-B， and the antioxidation system could be induced earlier than carbohydrate system.

Abstract: The seedlings of rice (xindao18) were exposed to UVB (10.08 kJ/(m2d1 )) irradiation following the pretreatment with three different implantation dosages of lowenergy N+ ions. Changes in the levels of the superoxide (POD)，superoxide dismutase (SOD)，catalase (CAT)， malondialdehyde (MDA)，glutathione (GSH) and soluble sugar were measured. The result showed that the UV-B irradiation on the seedlings of rice pretreated with lowenergy ions implantation could lead to increase activities in POD and SOD，and the maximum appeared on the dose of 2.0×1017 ions/cm2. Meanwhile，it made the content of GSH increased， and caused the activity of CAT and the content of MDA to be decreased. But there was no obvious change in soluble sugar. It was suggested that the rice pretreated by low energy ion implantation could enhance the antioxidation capacity and defensive ability when irradiated by UV-B， and the antioxidation system could be induced earlier than carbohydrate system. Therefore， the biological effects of UV-B irradiation on rice pretreated by low energy ion implantation were quite obvious.
